where would they get Hokage DNA? InGen? And even if it was received they would just clone them and make an amusement park...


Anyways, you'd think that it would have been mentioned once or twice whether or not he had such a famous father, and the name Uzumaki would initiate a responce (being as the 4th was a VERY powerful ninja) and it would have happened early on, like with Zabuza. If not then, at teh very, very, very least when he was up for chuunin exams the crowd would have said something.

you can't hide famous heritage... especially when he's such a trouble maker like Naruto... It would have been constant scorning: "You are a shame on your father's name"

And if for some reason he wanted it secret, he most likely wouldn't have painted on the stone sculpture...
